[Parenchyma sparing: evolution of the resective surgical approach of hepatic metastasis from the colorectum].

Abstract

Liver surgery for colorectal metastasis has moved toward a parenchymal sparing strategy in order to reduce postoperative liver failure, to resect an higher number of metastases and to allow a future re-resection. Patients undergone hepatectomy in our Department before and after 1999 were retrospectively compared. In the recent years surgery became more aggressive: a higher number of patients with multiple and bilateral lesions were treated. Short-term results improved in the recent series. After 1999, the rate of wedge resections was significantly increased with the same oncological radicality and with improved long-term results. Moreover, parenchymal sparing strategy allowed a higher re-resection rate in patients with liver recurrence.
